When rtl8xxxu_sta_add() accesses members of\nstruct rtl8xxxu_sta_info through sta->drv_priv, this results in a\nslab-out-of-bounds write.\n\nKASAN report on RISC-V (VisionFive 2) with RTL8192EU adapter:\n\n  BUG: KASAN: slab-out-of-bounds in rtl8xxxu_sta_add+0x31c/0x346\n  Write of size 8 at addr ffffffd6d3e9ae88 by task kworker/u16:0/12\n\nSet hw->sta_data_size to sizeof(struct rtl8xxxu_sta_info) during\nprobe, similar to how hw->vif_data_size is configured.
